Product details
This aftermarket TCV high pressure oil seal measures 105mm inner diameter, 130mm outer diameter and 7.5mm in height, manufactured in NBR nitrile rubber. It features an internal steel skeleton with external rubber coating, a short and thick primary sealing lip fitted with a garter spring, and a secondary dust lip designed to withstand medium system pressure up to approximately 0.5 MPa.
Importers, wholesalers and MRO buyers can submit RFQ with dimension, quantity, destination and working medium for a formal quotation. Standard production Lead Time is 7–15 days.
Features & Benefits
The TCV short and thick lip design reduces the pressure-bearing area on the sealing lip while maintaining rigidity, preventing lip inversion and leakage under medium hydraulic pressure that would cause a standard TC seal to fail.
Internal skeleton with external rubber coating provides structural rigidity and reliable static sealing in aluminum housings, handling pressure surges and shaft vibration in hydraulic pump and motor applications.
Double lip design with garter spring maintains uniform radial contact pressure; the primary lip retains pressurized hydraulic oil while the secondary lip blocks dust, mud and water spray.
NBR nitrile rubber offers good compatibility with hydraulic oils, mineral oils and greases, with dependable wear resistance for continuous rotary duty.
Standard 105x130x7.5mm dimensions match common metric TCV housings used in hydraulic pumps, motors and gearboxes across construction and industrial equipment.
This is an aftermarket replacement seal, not a genuine OEM part. Always verify shaft diameter, housing bore and system pressure before ordering.
- MOQ：Depends on spec; typically 100–5,000 pcs. Lead Time: 7–15 days. This SKU quantity confirmed on quotation.
Factory standard options are available for marking and packaging; confirm all requirements on RFQ.
Material & Process
- Sealing lip：NBR (nitrile butadiene rubber)
- Reinforcement：internal steel skeleton with external rubber coating
- Spring：carbon steel garter spring
- Pressure rating：up to approximately 0.5 MPa (medium pressure); confirm system pressure with RFQ.
Continuous working temperature: -30°C to +100°C; short-term peak up to +120°C. Confirm compound grade with RFQ for high-temperature applications.
Compatible fluids: hydraulic oil, mineral oil, gear grease
Applications & Compatibility
Commonly used for hydraulic pumps, hydraulic motors, gearboxes and transmissions in construction machinery, agricultural equipment and industrial drives. Application context commonly listed for this size — verify system pressure and shaft speed before order.
Aftermarket replacement. Verify shaft diameter, housing bore and system pressure before order.
Selection & Installation
Selection Tips
Confirm shaft ID 105mm, housing OD 130mm and seal height 7.5mm. Verify system pressure does not exceed the TCV medium-pressure rating and match NBR material to your hydraulic fluid type.
Installation Steps
- Thoroughly clean the shaft and housing bore; remove all burrs, old seal residue, rust and contamination.
- Lightly lubricate the sealing lip and shaft with compatible hydraulic oil. Do not install dry.
- Press the seal evenly into the housing using a proper installation tool, keeping it perfectly perpendicular to the bore.
- Do not strike the rubber lip or hammer directly on the seal. Avoid cocking or distorting it during installation.
- After assembly, rotate the shaft by hand to check for binding, then run under low pressure first and inspect for leakage.
Packaging & Delivery
Standard packaging: neutral polybag per piece, packed in export cartons. Typically 30–100 pcs per carton, adjustable on request.

FAQ
What is a TCV 105x130x7.5mm high pressure oil seal used for?
TCV 105x130x7.5mm NBR high pressure oil seal is used for hydraulic pumps, hydraulic motors, gearboxes and transmissions in construction and industrial equipment where medium system pressure up to approximately 0.5 MPa is present.
What are the full specifications of this 105x130x7.5mm TCV seal?
Size: 105mm inner diameter, 130mm outer diameter, 7.5mm height. Material: NBR nitrile rubber with internal steel skeleton and garter spring. Pressure rating up to approximately 0.5 MPa. Working temperature -30°C to +100°C.
What is the difference between TCV and standard TC oil seals?
TCV uses a short, thick sealing lip that reduces the pressure-bearing area while maintaining rigidity, allowing it to handle medium hydraulic pressure up to approximately 0.5 MPa. Standard TC seals are designed for near-zero pressure applications and can invert under pressure.
Is this 105x130x7.5mm TCV oil seal a genuine OEM part?
No — it is an aftermarket replacement seal. Always verify dimensions, housing bore and system pressure before purchasing.
How to install 105x130x7.5mm TCV high pressure oil seal without leakage?
1. Clean shaft and housing bore thoroughly to remove burrs and old seal residue. 2. Lubricate lip and shaft with compatible hydraulic oil; do not install dry. 3. Press seal evenly with a proper tool, keeping it perpendicular to the bore. 4. Do not hammer or strike the seal directly. 5. Run under low pressure first and check for leakage.
What is the MOQ and lead time for TCV 105x130x7.5mm oil seals?
MOQ depends on spec, typically 100–5,000 pcs. Lead Time is 7–15 days for standard production. This SKU quantity confirmed on quotation. Samples are available for stocked sizes.
What information should I send for an RFQ on this TCV high pressure seal?
Submit ID×OD×height in mm, system pressure, quantity, destination country, working medium and any custom requirements for a formal quotation.
Do you support custom logo and export packaging for this seal?
Factory standard options are available for marking and packaging. Confirm all requirements on quotation; Lead Time is 7–15 days for standard specs.
